I had setup a price trap targeted $31.5. In 14/05/2007 the stock penetrated $31.5 line, and my option filled at $31.4. Two days later, the stock retrace back to its $32 and $32.5 weekly trading band. My option had made 50% return already.

To my surprise, stock jumped $3.5 (10% of stock price) last night which is early than what I expected. Happliy, I have made over 300% ROI.

Hooray.
